Help improving my Mario-style jumping setup

As far as I can tell, the root of the problem seems to be that the Jump Collision Box’s events aren’t responding fast enough to launch the player character into the air before their Capsule Component comes into contact with the enemy’s, resulting in the player taking damage. If is indeed the cause of the problem then I need to somehow fix the response time of the Jump Collision Box so that it’s events will fire off immediately every single time it comes into contact with the enemy, as opposed to right now where the response time appears to be rather inconsistent.

Does anyone know how I can improve the Jump Collision Box’s response time? I’ve already enabled Continuous Collision Detection (CCD) on the player’s collision capsule, so what else can I do aside from maybe changing the “Position Solver Iteration Count”, although I still don’t know what that is and whether or not if that’ll be enough to fix issue.

So please provide any help that you can if you’re able, I desperately need the help.
